MK-1064

Research use only, not for human use.

A potent, selective, orally bioavailable Orexin 2 receptor (OX2R) antagonist with Ki/IC50 of 0.5/18 nM.

A potent, selective, orally bioavailable Orexin 2 receptor (OX2R) antagonist with Ki/IC50 of 0.5/18 nM; displays >100-fold selectivity over OX1R; promotes sleep and increases both rapid eye movement (REM) and non-REM (NREM) sleep in rats and dogs without inducing cataplexy; also decreases ACTH levels in rats.Sleep Disorder Preclinical(In Vitro):MK-1064 (30?mg/kg, oral administration) promotes sleep in rodents selectively through OX2R in Wild-type mice.MK-1064 (30?mg/kg, oral administration, 5 days) reverses the struggle behavior induced by CNO pre-treatment in rats.MK-1064 (1-5 mg/kg, intravenous injection/oral administration) shows moderate oral bioavailability and clearance in rat, dog, and rhesus monkey.

MK-1064 (30?mg/kg, oral administration) promotes sleep in rodents selectively through OX2R in Wild-type mice.MK-1064 (30?mg/kg, oral administration, 5 days) reverses the struggle behavior induced by CNO pre-treatment in rats.MK-1064 (1-5 mg/kg, intravenous injection/oral administration) shows moderate oral bioavailability and clearance in rat, dog, and rhesus monkey. Animal Model:Wild-type and OX2R knockout miceDosage:30 mg/kg Administration:Oral administration Result:Displayed active wake reduction accompanied by significant increases in SWS (slow-wave sleep) and REM (rapid eye movement) at time points up to 3.5?hours following treatment. Animal Model:Rat, dog, and rhesus monkey (Pharmacokinetics assay)Dosage:1, 2, 3, 5 mg/kg Administration:Oral administration (P.O.), intravenous injection (I.V.)Result:Pharmacokinetics profile of MK-1064.
